The present invention relates to a plate structure for a fluid flow, and more particularly, to a plate structure for a fluid flow that flattens at least a part of a circulation loop through which a fluid flows.

A vehicle cooling system is configured to circulate cooling water to cool heat rejecting components such as an internal combustion engine, a battery, and electric components. The vehicle cooling system includes a coolant circulation loop in which coolant circulates, and the coolant circulation loop includes various control components (valves, pumps, etc.) that control the flow of coolant, heat exchangers (radiators, etc.), and heat generating components (internal combustion engines, It is fluidly connected to a battery, an electric component, etc.).

For example, the vehicle cooling system includes an internal combustion engine cooling system that circulates coolant to cool the internal combustion engine of an internal combustion engine vehicle, a battery cooling system that circulates coolant to cool a battery of an electric vehicle, and electrical components of a powertrain of an electric vehicle. There is an electric component cooling system that circulates cooling water to cool, a battery-electric component cooling system that circulates coolant to cool the battery and electric components of an electric vehicle together, and the like.

The vehicle cooling system is mainly installed in a narrow front compartment of the vehicle, and the cooling water circulation loop of the vehicle cooling system may form a cooling water circulation loop with a plurality of tubes or a plurality of hoses. Dimensions (diameter, length, etc.) of tubes or hoses (diameter, length, etc.) Accordingly, the layout of the vehicle cooling system in the front compartment of the vehicle may be complicated due to the plurality of tubes or the plurality of hoses for forming the coolant circulation loop.

As the type or structure of a vehicle changes, the layout of the vehicle cooling system may be at least partially changed.
